To all whom it may concern:

Be it known that I, WILLIAM BECKER, a citizen of the United States, residing at Tron Mountain. in the county of Dickinson and State of Michigan, have invented a new and useful Improvement in Garbage- Burners, of which the following is a specification.

My object is to provide improvements in garbage-burners, to the end that they may be operated economically and effectively, and by which the ashes resulting from the burning of the garbage may be recovered and used for fertilizer, separated from metal and other objects which may be charged into the burner with the combustible garbage.

Referring to the accompanying drawings: Figure 1 is a plan sectional view of a garbage-burner constructed in accordance with my invention; and Figs. 2 and 3, enlarged sectional views through the burner, taken at the lines 2 and 3 respectively, on Fig. 1 and viewed in the direction of the arrows.

The combustion chamber of the burner, into which the garbage to be burned is introduced, is represented at 4, this chamber being constructed of any suitable material, as for example, fire-brick, and by preference being of oval form in plan and semi-spherical in cross-section, as shown. The chamber 4 is preferably provided with two inlets in its roof, one near each end of the chamber, for charging the garbage to be burned, into the chamber, one of these inlets being represented at 5, and preferably in the form of a shaft which opens at the lower end into the chamber 4 and at its upper end through a section 6 of a roadway upon which wagons carrying the garbage may be driven to dump the garbage into the burner, these inlets being provided with cover-sections as represented at 7.

The floor of the chamber 4 is represented at 8 and rising from this floor is ahousing 9 of any suitable material, preferably ordinary brick, which is spaced from the walls of the chamber 4 forming an air-space there between.

At one side of the housing is the smokeflue 10 which communicates with a passage 11 opening into the interior of the chamher 4.

Located in the front end of the burner are .two fireboxes 12 and 13, the firebox 12 being near the end of the chamber 4 farthest from the flue 10 and the firebox 13 at the opposite side of the center of the chamber 4, but at a comparatively slight distance from said center. These fireboxes are built into the front wall of the burner and are provided with grates 14 which are on a level with the floor of the chamber 4 and separate the fireboxes 12 and 13 from the ash-pits 15 and 16, re-

spectively, below them, curbs 12 and 13 respectively, being located at the rear portions of said grates. The fireboxes 12 and 13 are provided with doors 17 through which the fuel is introduced into the fireboxes, and the ash-pits have doors 18 through which the fuel-ashes may be removed.

Located in the front end of the chamber 4 are clean-out openings 19 and 20 arranged alternately relative to the fireboxes, and through which any suitable tool may be inserted into the chamber 4 to drag the garbage-ashes toward the front of the chamber 4, these clean-outs being equipped with doors 21. The floors of these clean-outs have grates 22 of the size generally used in fireboxes, and below these grates are chambers 23 provided with screen-partitions 24 preferably inclined slightly from the rear toward the front of the burner as shown of the one illustrated in Fig. 2, doors 25 and 26 being provided at the front ends of the chambers 23 above and below the screens 24, adjacent each clean-out.

In the operation of the structure the firebox 12 may alone be fired, or where conditions render it advisable, both it and the fire-box 13 may be fired, to providesuficient heat for burning the garbage in the chamber 4. The, heat from the firebox positioned, as stated, acts upon the garbage throughout its mass and where the heat from this firebox is sutficient to properly consume the garbage it alone need be fired. The heat from the firebox 13, Which is provided to supplement the firebox 12, acts only on the garbage at .the flue-end of the chamber 4, and where the chamber 4 is heavily charged with garbage, or the garbage, for any reason, requires relatively great heat, to consume it, the firebox 13 by being fired will, in conjunction with the firebox 12, serve to efl'ectually consume the garbage. Thus by the arrangement described provision is made for the maximum economical burning of garbage.

The ashes to which the garbage is reduced,

are drawn to a position upon the ates 22 by suitable tools inserted into the c amber 4 through the clean-outs 19 and 20. The ashes from the combustible portions of the garbage pass through the grates 22 and drop upon the screens 24 which are preferably of such mesh that only the relatively fine portions of the ashes pass into the bottom of the chambers 23, the grates screening out the relatively large particles and the screens 24 those particles which pass through the grates 22 and whichif allowed to remain in the ashes where the latter are to be used as fer-' tilizer, would be objectionable.

The air space between the chamber 4 and the housing9 is preferably in communication with the atmosphere through the medium of a passage which opens into this space and into the ash-pit 15, therebyproviding for the circulation of air in said airspace which hasa cooling efiect on the walls of the structure.

What I claim as new and desire to secure by Letters Patent, is:

A garbage-burner comprising a housing,

a combustion chamber within said housing in separated relation fromthe wall thereof and into which the garbage to be burned is introduced, a smoke outlet from said combustionchamber, a smoke flue at one end of said housing, a grated fire-box extending into the combustion chamber at the end thereof opposite the smoke flue, a supplementary grated fire-box extending into the WILLIAM BECKER.
